Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal fitting for mounting an interior panel for a tunnel, and more particularly to a metal fitting for mounting an upper part and a lower part of the interior panel.

[0002]

2. Description of the Related Art As shown in FIG. 6 and FIG. 7 showing its front view, in a tunnel such as a road, an interior panel P for makeup is attached to a tunnel base wall W at a corner portion 50a and an intermediate portion 50b thereof. It is attached by hardware. Conventionally, as shown in FIG. 8, the mounting hardware of the interior panel P includes a base-side metal fitting 51 mounted on a tunnel base wall W, a panel upper-side metal fitting 61 and a panel lower-side metal fitting 71 mounted on upper and lower portions of the interior panel. Consists of.

The base metal piece 51 is composed of a fixed metal piece 52 having a substantially L shape in a side view and a locking metal piece 55 having a substantially L shape in a side view and having a tip portion bent and raised. The fixed metal piece 52 is for fixing the panel upper metal piece 61, and is attached to the anchor bolts B provided on the base wall W at required intervals.
The vertical piece 54 is fixed with the horizontal piece 53 facing upward. The locking metal piece 55 is for locking the panel lower metal piece 71, and the vertical piece 57 is fixed to the anchor bolt B of the base wall with the horizontal piece 56 facing down.

On the other hand, the panel upper side metal 61 is substantially L in a side view.
The vertical piece 62 is in the shape of a letter and is fixed to the upper part of the rear surface of the interior panel P by bolts, and the horizontal piece 63 is the fixed metal piece 5.
The second horizontal piece 53 is mounted and bolted. Further, the panel lower side metal piece 71 is made of an engraved metal piece, and the upper vertical piece 72 is fixed to the lower part of the rear surface of the interior panel P by a bolt, and the lower vertical piece 73 is a rising piece of the locking metal piece 55. It is inserted inside 58 and locked.

However, in the metal fitting for mounting the interior panel for the tunnel, the panel upper metal fitting 61 and the base metal fitting 51 are coupled by bolting the horizontal pieces 63 and 53 to each other, and therefore the bolt head. A space corresponding to the outer diameter of the portion 81 or the nut 82 and a space for tightening the bolt are required between the rear surface of the interior panel P and the front surface of the base wall W. As a result, the protruding size of the interior panel P from the base wall W becomes large, and the usable space in the tunnel is made small.

Further, the lower part of the interior panel P is sandwiched between the lower metal part 71 made of a lightning-shaped metal part and the back surface of the interior panel P, and the base metal part (locking metal part 55) is sandwiched, while the upper part of the interior panel P is the above-mentioned part. Since the panel upper side hardware 61 and the base side hardware (fixed hardware 52) are fixed by bolts as described above, there is no play when mounting the interior panel.

Therefore, if an error in the mounting angle of the anchor bolt B or a molding error in the metal fittings on the substrate side occurs, unexpected stress may be applied to the interior panel P, causing cracks or large cracks. Sophistication is required in the installation work of the and the interior panel. Particularly, when the tunnel base wall W has an arc shape, it is difficult to accurately attach the anchor bolt and the interior panel, and when the interior panel is a tile on the panel base, cracks occur. Even if there is no stress, there is a concern that it will act on the adhesive surface of the tile and cause the tile to peel off.

[0008] Further, for the panel upper side metal piece and the panel lower side metal piece which are vertically adjacent to each other, it is troublesome to prepare two kinds of base side metal pieces (the locking metal piece 55 and the fixed metal piece 52), and the two types thereof. In order to fix each of the base metal parts to the base wall, it was necessary to attach two anchor bolts close to each other, which was a workability problem.

Although it is possible to attach the panel upper side metal piece and the panel lower side metal piece adjacent to each other to a common base side metal piece, there is a troublesome problem for the following reason. That is, in general, the bolt holes (attachment positions of metal objects) to the panel are designed to facilitate the panel attachment work.
It is set to a position that eliminates the directionality of the top, bottom, left, and right of the panel.
Therefore, since the bolt holes of the vertically adjacent panels are on the same line along the vertical direction, when the board side hardware is common as described above, the interference between the panel upper side metal object and the panel lower side metal object or the base The interference between the anchor bolts of the side hardware and the panel upper side and the panel lower side hardware had to be considered, and the design was not easy.

[0010]

The space inside the tunnel can be made wider than before, and the interior panel can be mounted with play. Further, the present invention provides a metal fitting for mounting an interior panel for a tunnel, which has a small number of parts and simplifies construction work.

On the other hand, the panel upper side metal member 21 includes vertical pieces 22,
It has a substantially Z-shape in a side view and an L-shape in a front view having an intermediate portion 25 between 26. One of the vertical pieces 22 (which faces downward when used) has a bolt insertion hole 23 for fixing to the interior panel. The other vertical piece (upward when used) has a shape in which the portion corresponding to the upper position of the fixing bolt insertion hole 23 of the downward vertical piece 22 is lacking, and the fixing bolt to the interior panel is formed. A fixing bolt insertion hole 27 for fixing the base-side hardware 11 is formed at a position laterally separated from the insertion hole 23. Although the fixing bolt insertion hole 27 of this embodiment is formed by a notch formed with a desired depth from the right end of the vertical piece 26, it may be a closed perfect circle, an ellipse, or the like.

As shown in FIGS. 2 to 5, the upper metal piece 21 of the panel is provided on the upper rear surface of the interior panel P, and the vertical piece 2 is provided.
The fixing bolt 28 is inserted through the second bolt insertion hole 23. At this time, the vertical piece 26 in which the fixing bolt insertion hole 27 is formed in the base-side hardware 11 is made to face upward.

The lower metal piece 31 of the panel includes vertical pieces 32,
It has a substantially Z shape in a side view having an intermediate portion 34 between 35.
The one vertical piece 32 (upward when used) has a bolt insertion hole 33 for fixing to the interior panel, and the other vertical piece 35 (downward when used) is a vertical piece of the base metal piece. A locking piece for the one-side locking hole 17 is formed.

As shown in FIGS. 2 to 5, the lower metal piece 31 of the panel is provided on the lower portion of the back surface of the interior panel P with the vertical piece 3
The fixing bolt 36 is inserted through the second bolt insertion hole 33. At that time, the other vertical piece 35 is made to face downward.

The mounting hardware 10 thus formed
As described above, the base metal 11 is attached to the base wall W of the tunnel, the panel upper metal 21 is the upper back surface of the interior panel P, and the panel lower metal 31 is the interior panel P.
Is attached to the lower back surface of each. At this time, in the interior panel P, the bolt holes for mounting the hardware are aligned at a position where the directionality of the interior panel P is lost and including the anchor bolt B of the tunnel base wall W along the vertical direction. , The panel upper side metal fitting 21 and the panel lower side metal fitting 3 are formed in the vicinity of the upper and lower corners of the interior panel P and in the vicinity of the upper and lower intermediate parts thereof, and through the hardware mounting bolt holes.
1 is attached to the back surface of the interior panel P. Then, as shown in FIGS. 2 and 3, the downward vertical piece 35 of the panel lower side metal fitting 31 at the lower part of the interior panel P is the base wall W.
It is inserted and locked in the vertical piece locking hole 17 formed in the horizontal piece 16 of the base metal piece 11 at.

Next, the upward vertical piece 26 of the panel upper side metal fitting 21 at the upper part of the interior panel P is superposed on the vertical piece 12 of the base side metal fitting 11 as shown in FIG.
Bolt insertion holes 14 formed in the vertical pieces 12 and 26 of 21,
As shown in FIG. 5, a fixing bolt 37 is inserted into the screw 27 and screwed with a nut 38. Thereby, the interior panel P is attached to the base wall W. At that time, as shown in FIG. 4, the panel upper side metal member 21 has a substantially L shape in a front view,
Since the upward vertical piece 26 has a shape that is missing in a portion of the downward vertical piece 22 above the fixing bolt insertion hole 23, the upward vertical piece 26 does not hit the anchor bolt B.

As in this embodiment, when the bolt insertion holes 14 and 27 formed in the vertical pieces 12 and 26 of the base metal piece 11 and the panel upper metal piece 21 are notches, the bolt 37 is inserted into the insertion hole 14. , 27 is easy to fit. Even if the notch is formed in either the base-side metal fitting 11 or the panel-side metal fitting 21 and the bolt insertion hole of the other metal fitting is a hole with a closed peripheral edge, the effect of easy fitting of the bolt can be obtained.

Further, as described above, the vertical piece locking hole 17 in the horizontal piece 16 of the base metal piece 11 is made larger than the width and thickness of the vertical piece 35 of the lower metal piece 31 of the panel by a predetermined amount, and the vertical length thereof is increased. If play is allowed between the one-side locking hole 17 and the vertical piece 35 on the panel lower side 31, when the panel upper side metal member 21 is bolted to the base side metal member 11, there is an attachment error of the anchor bolt B or the like. However, the above play can be dealt with, and unexpected stress can be prevented from being applied to the interior panel P.

Furthermore, the axial direction of the fixing bolt 37 for the base-side metal fitting 11 and the upper metal fitting 21 and the axial direction of the anchor bolt B for mounting the base-side metal fitting 11 coincide with each other, and the bolt 37 and the nut 38 The head is parallel to the back surface of the interior panel P. Since the thickness of the bolt head and the nut along the axial direction of the bolt is smaller than the outer diameter of the bolt head and the nut orthogonal to the axial direction of the bolt, the back surface of the interior panel P is smaller than that when the conventional mounting hardware is used. The space between the base wall W can be narrowed.

[0026]

As shown and described above, according to the mounting hardware of the present invention, the vertical pieces of the base-side metal are overlapped with each other and fastened together by the fixing bolts. The head of the bolt and the nut are substantially parallel to the surface of the base wall and the back of the interior panel. Since the head and nut of this bolt have a smaller axial thickness than the outer diameter in the diameter direction, even if the distance between the interior panel back surface and the base wall surface is narrowed, the bolt head and nut are Does not hit the back of the panel or the surface of the base wall. Moreover,
When tightening the bolts, the operating direction of the tool such as the wrench is almost parallel to the back surface of the interior panel and the surface of the base wall, so it is difficult to install the interior panel even if the space between the back surface of the interior panel and the surface of the base wall is narrowed. It will never happen. Therefore, according to the mounting hardware of the present invention, the distance between the interior panel and the base wall can be reduced as compared with the conventional mounting hardware,
This has the effect of expanding the space inside the tunnel.

Further, according to the mounting hardware of the present invention, the vertical piece of the panel lower metal fitting attached to the lower portion of the interior panel is inserted into the vertical piece locking hole formed in the horizontal piece of the base metal fitting. The lower part of the interior panel is locked. for that reason,
If the vertical piece locking hole is formed to be larger than the vertical piece of the lower metal part of the panel by a predetermined amount, a play can be provided when mounting the interior panel, and an unexpected damage force such as a twist is applied to the interior panel. There is an effect that can prevent.

Further, in the mounting hardware of the present invention, the panel upper hardware is substantially L-shaped in plan view, and the fixing bolts and the anchor bolts for the base metal are separated laterally from each other. It is possible to attach the panel upper side hardware and the panel lower side hardware with one base side hardware without interference between the hardware and the panel lower side hardware and the interference between the hardware and the anchor bolts. Therefore, it suffices to provide one anchor bolt at that portion, and the construction work becomes extremely good. Moreover, since the number of parts is reduced, parts management and the like become rational.
